o
While using the MPOD for measurement or calibration (see further below), see to it
that there isn’t any object likely to disturb measurements (ferrous objects, watches,
mobile phone…)
o
MPOD should be used far from motorized chairs or beds.
o
Only small magnets are accepted in the same room (i.e. whiteboard magnet), but
must be kept far from the MPOD (>50 cm), as they might cause a serious decrease in
the systems accuracy.
o
DO NOT TO PUT THE MPOD IN CONTACT WITH A MAGNET AS IT WILL MAKE IT
PERMANANTLY USELESS.
o
The presence of strong magnetic field generating machines (like MRI) is not adapted
to the use of MPOD™.

CHARACTERISTICS AND ENVIRONMENTAL CONDITIONS
Usage conditions
Temperature
Stable between 0°C and 35°C
Maximum dynamic acceleration measured
-8g à 8g
When not using gyroscopes, orientation measures are valid for static and quasi static
positions. When using gyroscopes body motion must be limited to sensors limit.
The measured orientation parameter is valid in a uniform or quasi uniform magnetic field between -6
gauss and +6 gauss
1
Maximum Shock resistance
4600 g for a time of 0,5 ms
MPOD should not be thrown away violently.
It is however resistant to shocks in normal
conditions of use.
Magnetic field survivability
10 000 Gauss
Maximum rate of magnetic field tolerated before miss-
calibration
20 Gauss
Packaging and transport conditions
Temperature
Between -20°C and 35°C (For 6 month
maximum)
45°C (For 1 month maximum)
Shock resistance
4600 g for a time of 0,5 ms
Magnetic field survivability
10 000 Gauss
Maximum rate of magnetic field tolerated before miss-
calibration
20 Gauss

MotionDevTool v2.0.4 software automatically checks if this condition is verified during recording of the
movement signature. An alarm is emitted in case of magnetic disturbance. If there is no alarm, the user is
under desired conditions.
